For over 50 years, the compact, fluoropolymer (PTFE/FEP/PFA), Sanitary Insert Valve has been used as the most economical solution to providing a check valve in a new or existing sanitary piping system. This valve style is designed to fit into grooved-end clamp-type fittings. Since the Sanitary Insert Valve replaces the gasket normally used with clamp joints, no extra space is required to accommodate the valve.
Two different types of Sanitary Insert Valves are available. They are distinguished by the following designations in their part numbers:
TC - Designates Tri-Clamp® fittings manufactured by Alfa Laval Inc. as well as Waukesha Cherry-Burrell® S-Line Series of fittings.
In addition applicaitons where the maximum allowed oerating pressure is 0.5 bar (7.2 psi) or less, do not fall under the PED, regardless of the valve style.
